On the price & condition, I've no clue. What I can tell you is that the terms and conditions of sale are somewhere on that site, because I've looked at them before. If I recall correctly (& I make no promises on that), it's "as is," and you have to pick it up. One of the ads I looked at today said something like "GL will tail-gate load." I would not expect the brass to be in the best shape, and a certain percentage will probably only be fit for sending to a scrap metal dealer. That said, I also suspect you'd get enough usable brass that it might be worthwhile, if you had enough reloading buddies with pickup trucks to haul it home. The question then becomes, "How many buddies do I need to split up a ton or two of fired brass?"
Edited to add: Oh, and in answer to that question, I did the math on something like 6,000 lbs of .223 brass one time. Now, it's been a while, so don't hold my feet to the fire on the numbers, but IIRC, I figured out that if I got it all reloaded, I'd have to shoot something like 220 rounds per day, every day, regardless of weather, and live to be ~85 to get through it all.
